Abstract
A brake caliper includes a caliper body. The caliper body has a first accommodation trough and a second accommodation trough. The first accommodation trough is provided with at least one piston and two first brake linings pushed by the piston. The second accommodation trough is provided with two second brake linings. The two second brake linings are connected with a drive unit. When the user pedals the brake pedal of a vehicle, the brake master cylinder of the vehicle pushes the piston to link the two first brake linings to clamp both sides of the disc to perform foot brake. When the user activates the electric parking brake of the vehicle, the drive unit will push the two second brake linings to perform electronic hand brake.
